Small cerebellar infarction with a benign outcome occurs more frequently than a massive infarction with brainstem compression. Retrospective CT studies have shown it. These infarcts are more often localized in the superior hemisphere of the cerebellum which semiology is not well known. Some reports pointed out that an acute cerebellar infarction in the PICA territory may mimic labyrinthine lesion. The authors report a case of an acute small cerebellar infarction in the SCA territory presenting as a dysarthria and unsteadiness, involving the left lobulus semilunaris superior, in a paravermal zone, on CT scan.
小脑小梗死预后良好的情况比伴有脑干受压的大面积梗死更为常见。回顾性CT研究已证实了这一点。这些梗死更常位于小脑上半球,其症状学尚不为人熟知。一些报告指出,小脑后下动脉(PICA)区域的急性小脑梗死可能类似迷路病变。作者报告了一例发生在小脑上动脉(SCA)区域的急性小脑小梗死病例,表现为构音障碍和步态不稳,CT扫描显示病变位于左侧上半月小叶,在旁中央小叶区。
